Week 6 Worksheet Exercises

Hierarchies: Multilevel models

Aims

Setup

Create a worksheet document

In Week 1 you set up R and RStudio, and an RProject folder (we called it “HSS8005_labs”) with an .R script and a .qmd or .Rmd document in it (we called these “Lab_1”). Ideally, you saved this on a cloud drive so you can access it from any computer (e.g. OneDrive). You will be working in this folder. If it’s missing, complete Exercise 3 from the Week 1 Worksheet.

Create a new Quarto markdown file (.qmd) for this session (e.g. “Lab_6.qmd”) and work in it to complete the exercises and report on your final analysis.

Load R packages

Using functions learnt in Week 1, load (and install, if needed) the following R packages:

• tidyverse
• easystats
• gtsummary
• ggformula
• sjlabelled
• ggeffects
• marginaleffects
